How can I find what chip I have (what version of raspberry pi) with Ubuntu 18.04 server for arm64? What file can I check or what command can I run? /proc/cpuinfo does not have return useful information, just some generic details without mention of the pi.

  You might be at an impasse with this because the RP does not support SMBIOS or DMI that allows for reading board information. It might also be something you might have to file as a bug to get the revision read in the cpuinfo.

The command lscpu is what you look for. Here's an example output of the command (taken on my Raspberry Pi 3B+):

lscpu

Which produces the following output:

Architecture: armv7l
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
Model: 4
Model name: ARMv7 Processor rev 4 (v7l)
CPU max MHz: 1200,0000
CPU min MHz: 600,0000
BogoMIPS: 38.40
Flags: half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32

---

Another option is the inxi command (you might have to install it if not present with sudo apt install inxi). The flags to use are as follows:

inxi -C

Which produce the following output:

CPU: Quad core ARMv7 rev 4 (v7l) (-MCP-) (ARM) 
 clock speeds: max: 1200 MHz 1: 1200 MHz 2: 1200 MHz 3: 1200 MHz 4: 1200 MHz

---

As for identifying which chip is build on your board you can check the chip on the board as well the manufacturers website for info and as well as the different selling outlets for getting technical details.

  Thank you, that definitely gives extra information. However, the model name when I run lscpu is listed as Cortex A-53, which is on both the pi 2 and 3 I believe. Do you happen to know of a more specific command/file which can distinguish between these two boards?

  Normaly the board type and revision is printed on the board too, so you might be able to check that, otherwise I'm out of clues.

  I see. I know what my board is, but a library maintainer needs this info to adjust his library to work with my hardware and software. Tried inxi, it also gives generic output only. Really appreciate the help though.

  As for the library you want to use, there's only one question. is there a library which provides the same function you need or not. This is the information you can get from your machine program wise. On desktop computers there might be more information to get on the CPU version, the raspberry lacks in that regard a bit as putting all this information in some chips is adding to the costs.

  Current inxi (3.0.xx) has way better ARM support than legacy inxi (2.xx.yy), which I think is what you find in 18-4. That will do its level best to give quite a bit of information about the actual SBC device itself. On rasberry pi 3 the only thing it's not catching is the mmc wifi device, which is too complicated to grab data on, but otherwise the report for pi 3 is quite complete in new inxi. Legacy inxi had only rudimentary ARM support. Compare inxi -Fxxx or -v7 on legacy and current on any pi device and you'll see what I mean.
